To all whom it may concern:

Be it known that I, WILLIAM R.'HARTUNG, a citizen of the United States, residing at Connell, in the county of F ranlilin and State of Washington, have invented certain new and useful Improvements in Processes for Preventing Carbon. Deposit in Engine-Cylinders, of which the following is aspecification.

My invention relates to improvements in processes' for preventing carbon deposits in engine cylinders, more particularly in the cylinders of the internal combustion engines used on automobiles, trucks, and similar motor vehicles, and it conslsts 1n the steps hereinafter set forth.

An object of my invention is to Provide a process for preventing carbon deposit which does not necessitate the use of chemical carbon removers or the use of steam, or other means which are ordinarily employed in preventing carbon deposit.

A further object of my invention is to provide a process for preventing carbon deposit which not only prevents these deposits but actually adds to the life of the engine,

Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claims.

In carrying out my invention I chill the interior of the engine cylinder and the piston head so as to produce a hard glazed surface. The maternal of the engine cylinder and piston should be of such a nature as to adapt itself to the chilling and the hardening. These parts are carefully machined so as to be made as smooth as possible and then the parts are chilled in any suitable manner, such as by heating them and suddenly cooling them in any suitable cooling solution or Specification of Letters Patent.

liquid, so as to produce a very smooth and very hard surface wherever the carbon is likely to lodge. 4

Where the interior of the cylinder and the piston head has been chilled, the carbon is unable to find lodgment. Part of it is'consumed and part of it passes outwith the ex haust gases. The power of the engine is materially increased and as a consequence, the working'of the engine as awhole is rendered more efficient, since not only is greater power obtained from a given quantity of fuel, but the life of the engine is prolonged dueto the chilling process which hardens the interior of the cylinder and prevents the Wearing away, which might otherwise occur.

I claim 4 1. The herein described process of preventing carbon deposit inthe cylinders of an internal combustion engine which consists in chilling the interior walls of said cylinders.

2. The herein described process/of preventing carbon deposit in internal combustion engines which consists in chilling the in'terior walls of the cylinder and the piston head to produce a smooth, glazed surface whereby the carbon is prevented from finding lodgment.

3. The herein described process of preventing carbon deposit in internal combustion engines which consists in chilling the interior walls of the cylinder and the piston head thereby producing a hard, smooth, glazed surface whereby the carbon is prevented from finding lodgment.
